Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man-machine interface for transmitting an operator's intention to a device by touching an operation button displayed on a monitor screen with a finger or a pen or clicking with a mouse. The present invention relates to a medical device having a soft key as a keypad, and relates to a medical device erroneous operation prevention device configured to prevent erroneous operation of an operation button.

[0002]

2. Description of the Related Art Medical devices include X-ray diagnostic devices, digital radiography, digital fluorography, X-ray computed tomography devices, magnetic resonance imaging devices, and the like. A wide variety of devices are known, including various medical image inspection devices such as a nuclear medicine diagnostic device, an ultrasonic diagnostic device, and an electronic endoscope device, a therapeutic particle accelerator for treatment, a hyperthermia device, and an extracorporeal shock wave calculus crushing device. However, they are all built precisely with advanced technology.

[0003] However, the more advanced and sophisticated the technology, the more difficult it is in general to operate and the more likely it is to make an operation error. Since mistakes are related to human life, efforts have been made to make operation as easy as possible so that operation errors do not occur. In particular, among the various operation buttons provided in various devices, for an operation button that starts a process that may lead to a serious accident if the operator performs an incorrect operation, for example, as a means for preventing an operation error, Cover the operation buttons with a transparent cover so that the operation buttons cannot be operated unless the cover is opened.
In some cases, when the first stage is pressed, the second stage can be pushed, and the second stage is also pushed to start processing.

Recently, operation buttons are displayed in an interactive screen displayed on the screen of a computer, and the operation buttons are touched with a finger or a pen or clicked with a mouse (hereinafter, these operations are referred to as “convenient”). As a result, the number of devices having a soft key as a man-machine interface for transmitting the intention of the operator to the device side is increasing. In such a soft key, as a means for preventing an erroneous operation, when the operation button is pressed, a message for confirmation is displayed on the screen, and the intention of the operator with respect to the message is determined as “Yes” or “ Pressing the "No" key again will generally indicate this.

[0005]

However, when the operation buttons are covered with a transparent cover, the cover must be opened each time the operation is performed, and the operation is troublesome. In addition, since the two-stage operation button is a mechanical mechanism, it has a complicated structure and needs to be specially manufactured according to each application, and thus has a problem of lack of versatility.

[0006] Further, the display of a message as a countermeasure against erroneous operation of a soft key requires an operator to read and understand the message and to touch or click to express the operator's will for confirmation. It has to be executed, and there is a disadvantage that the flow of processing and thinking is interrupted. Such operations are:
There is not much problem with operating a PC used in the office, but in the case of medical equipment used in hospitals,
When the operation is focused on examination, diagnosis or treatment, there is an urgency problem and the operation is very troublesome and inconvenient. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has been made to prevent erroneous operations while facilitating the operation of soft keys.

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 performs a desired process by touching or clicking an operation button displayed on a screen of a display device. In the medical device having the soft keys to be executed, the operation of the operation button is continuously operated for a predetermined time or the operation is repeated a predetermined number of times within a predetermined time to start execution of a desired process. It is assumed that.

[0008] This eliminates the need for an act of reading and understanding the message for confirmation and an extra operation of pressing an operation button in order to express the operator's will for confirmation, and the flow of processing and thinking is not required. Erroneous operation can be prevented while the operation of the soft keys is facilitated without interrupting the operation.

The invention described in claim 2 is the first invention.
In the medical device erroneous operation prevention device according to the above, whether the operation of the operation button is not continued for the predetermined time,
Alternatively, when the number of operations of the operation button does not reach the predetermined number within the predetermined time, the operation of the operation button up to that time is invalidated.

As a result, similarly to the first aspect of the present invention, it is possible to easily operate the soft keys and prevent erroneous operations. According to a third aspect of the present invention, in the medical device for preventing erroneous operation of the medical device according to the first or second aspect, the elapsed time of the predetermined time or the number of times the operation button is operated is indicated by a number on the operation button Is displayed.

Thus, the operator can recognize the number displayed on the operation button, the elapse of a predetermined time, and the number of times of operation of the operation button, and the operation becomes extremely easy to prevent erroneous operation. It can be more reliable.

Further, according to a fourth aspect of the present invention, in the device for preventing an erroneous operation of a medical device according to the first or second aspect, the operation buttons are divided into an arbitrary number, and the divided part is divided into , Or flashes sequentially with time or each time the operation button is operated, or is sequentially changed to a display color different from the initial state.

[0013] Thus, the operator can recognize the elapse of time such as a time limit and the number of times of operation of the operation button from the blinking of the operation button or the change of the light emission display, and the operation becomes extremely easy. In addition, erroneous operation can be more reliably prevented.

[0014]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of an apparatus for preventing erroneous operation of a medical device according to the present invention; FIG. The erroneous operation prevention device for a medical device according to the present invention is intended to prevent an erroneous operation in a soft key operation, and its concept will be described first.

That is, the soft key is an operation button displayed on the screen of the display device, and a desired process is executed by pressing the operation button with a finger or a pen or clicking with a mouse. Things.
Therefore, in the present invention, by continuing to press the operation button for a predetermined time or repeating the press a predetermined number of times within a predetermined time, execution of a desired process is started, and the press is interrupted within a predetermined time, If the number of repetitions does not reach the predetermined number, the operation so far is invalidated so that the desired processing is not executed.

As described above, by continuously pressing the operation button for a predetermined time or by pressing the operation button a predetermined number of times within the predetermined time, the processing corresponding to each operation button is started. If the press is interrupted halfway, the process is not started, so that erroneous operation can be prevented while facilitating operation of the soft keys. Therefore, the act of reading and understanding the message for confirmation and the extra operation of pressing the operation button to express the operator's will for confirmation are not required, and the flow of processing and thinking is interrupted. The inconvenience of the operator is also eliminated, and the operator can concentrate on examination, diagnosis, and treatment.

Further, according to the present invention, it is possible to display the elapsed time and the number of operations on the operation buttons by numbers, or to divide the operation buttons into an arbitrary number, and to blink these divided portions sequentially with the passage of time. The display is sequentially displayed in a light emission color different from the initial state, so that the operator can recognize the status of the operation being performed and the lapse of time.

A number is displayed on the operation buttons, and the operation buttons divided into an arbitrary number are sequentially blinked or lit to visually indicate the elapsed time and the number of operations to the operator. Recognition makes it possible to more reliably prevent erroneous operations. Furthermore, since it is possible to provide operation buttons of various shapes without requiring a mechanical mechanism such as a hard key, even if the same device is used, it is necessary to use the operator's proficiency and the importance of processing. The effect that the setting suitable for the environment becomes possible can be expected.

When the execution of the process is started by pressing the operation button for a predetermined time, the process is executed with a delay of a predetermined time. Shall be. In addition, in the case where the execution of the desired process is started by repeating the press a predetermined number of times within the predetermined time, it is necessary to repeat the press a predetermined number of times within the predetermined time. This is called a limit function.

FIG. 1 shows a predetermined time (time limit).
1 shows an embodiment in which the number of times the operation button 1 is operated is counted down on the operation button 1, and in this embodiment, a five-stage countdown display is provided. That is, as shown in FIG. 1A, when the number of the counter displayed on the operation button 1 is "5", the counter is in the OFF state, and each time the operation button 1 is operated, the number of the counter decreases by one. 1 (b), FIG. 1 (c)..., And when the operation button 1 is operated five times, the number of the counter becomes “0” as shown in FIG. 1 (f). At this time, it is turned on to execute a predetermined process. However, if the number of operations of the operation button 1 within a predetermined time (for example, one second) is less than five, the operation button 1 is reset as the predetermined time elapses.
The process does not execute.

Next, FIG. 2 shows that the operation buttons 1 are divided into an arbitrary number, and the divided parts are sequentially illuminated according to the elapse of a set time so that the elapse of time can be notified. The operation button 1 is sequentially illuminated every time the operation button 1 is operated within the time period (time limit) to notify the number of operations. That is, FIG. 2A shows an embodiment in which the circular operation button 1 is divided vertically and horizontally into four parts, and FIG.
Shows an embodiment in which a circular operation button 1 is concentrically divided into three. FIG. 2C shows an embodiment in which the rectangular operation button 1 is divided vertically and horizontally into four parts.
(D) shows an embodiment in which the rectangular operation button 1 is divided horizontally into three parts.

Of the operation buttons 1 shown in FIG. 2,
(A1), (b1), (c1), and (d1) respectively show an initial state (OFF state) in which no light is emitted, and each time a set time (for example, 0.2 seconds) elapses, or Each time the operation button 1 is operated, one of the divisions emits light. Therefore, (a2), (b)
2), (c2) and (d2) indicate that the operation button 1 is 1
Times, or when one set time has passed,
(A3), (b3), (c3), and (d3) show states in which the operation button 1 has been operated twice and two set times have elapsed, respectively. Then, (a5), (b4), (c)
5) As shown in (d4), when the entire operation button 1 finally emits light, it is turned on to execute a predetermined process. Of course, if the number of operations of the operation button 1 within a predetermined time (for example, one second) is less than the predetermined number, the operation is reset as the predetermined time elapses in the same manner as in FIG.

The light emission color of the operation button 1 may be any color as long as the color can be distinguished from the initial state. It should just turn red. The time limit and the set time can be arbitrarily determined.

FIG. 3 shows a modification of FIG. 2D in which the operation buttons 1 are sequentially turned on and off every time the set time elapses or each time the operation buttons 1 are operated within a predetermined time (limit time). Next, an embodiment in which the number of display modes is increased with the operation buttons 1 having a small number of divisions by shifting the blinking state to the lighting state when the state becomes the blinking state is described.

That is, FIG. 3A shows the initial state (OFF
FIG. 3B shows a state in which one display is blinking after one operation or one set time has elapsed. FIG. 3D shows a state in which all three displays are blinking due to three operations or three set times.
FIG. 3E shows a state in which the first display shifts from blinking to lighting after four operations or four set times have elapsed, and the other two displays are blinking. Then, FIG. 3 (g)
Indicates a state in which all three displays are turned on after six operations or six set times, and in this case, the display is turned on to execute a predetermined process. If the number of operations of the operation button 1 within the time limit is less than six, it is needless to say that the operation button 1 is reset as the time limit elapses.

FIG. 4 is a block diagram showing an embodiment of the apparatus for preventing erroneous operation of a medical apparatus according to the present invention, which has the above-mentioned operation buttons 1 as soft keys. I do.

Next, a part of the CPU 12 which is a control center of the entire apparatus according to the present invention, which exerts a function of preventing erroneous operation, and its operation will be described. FIG. 5 shows the main components of the CPU 12 that exerts the function of preventing an erroneous operation in association with FIG. The CPU 12 has a processing control unit 121 that implements a predetermined algorithm, reads an input operation such as a button operation from the mouse 162 of the input device 16, and transmits an input data reading unit 122 to the processing control unit 121. A system time monitor 123 for monitoring the system time held by the main body 11, that is, the time by the timer 15, the system time monitor 1
23, the processing control unit 12
Under the control of 1, it is associated with an elapsed time calculation unit 124 that performs an operation related to time, such as a start time of a button operation by the mouse 162 read by the input data reading unit 122 and a set time limit.

The storage device 14 stores operation button attributes for storing attributes such as the shape of the operation buttons 1 displayed on the display device 17, the set time, the number of display divisions, the time limit, and the number of operations for each operation button 1. The processing unit 121 includes a processing unit 141. The attribute of the operation button 1 stored in the operation button attribute storage unit 141 is registered or changed by the keyboard 161 or the like via the input data reading unit 122, and the result is stored. Further, when the operator operates the operation button 1 displayed on the display device 17, the processing control unit 121 changes the display state of the operation button 1 in response to the operation (changes the number of the counter, A button display data creating unit 125 for creating data for causing a divided portion to emit light, and an external device for issuing a processing command from the medical device main body 11 to the external processing device 18 via the external interface device 19. It is also associated with the control unit 126.

Next, the operation will be described. The processing control unit 121 first reads the attribute of the operation button 1 from the operation button attribute storage unit 141 and
5, the display data of the operation button 1 is created, and the operation button 1 based on the created data is displayed on the display device 1.
7 is displayed. When the operator starts operating the operation button 1, the operation status is read by the input data reading unit 122, and the read operation status is transmitted to the processing control unit 121. At the same time, the processing control unit 12

Then, the processing control unit 121 obtains the calculation result from the elapsed time calculation unit 124, and if it has reached the time to issue the processing instruction, issues a processing instruction to the external device control unit 126 and the like, and reaches the time. If not, the calculation result and the attribute related to the operation button 1 from the operation button attribute storage unit 141 are sent to the button display data creation unit 125, and if the operation button 1 is of a format for displaying numbers as shown in FIG. , The display of the counter is reduced by one, and FIG.
Alternatively, in the case of the shape as shown in FIG. 3, display data corresponding to the shape is created and displayed on the display device 17.

Such an operation will be described more specifically with reference to the flowcharts of FIGS. FIG.
5 is a flowchart illustrating a delay function of the operation button 1. ST (step) 1 indicates that the operation start flag is OFF as an initial state. Next ST2
Indicates a state of waiting for input of an operation signal when the operation button 1 is pressed or the press is stopped (released). Then, in ST3, it is detected whether or not the operation button 1 is pressed. If the operation button 1 is not pressed, the process is terminated as it is. . Then, when the operation button 1 is pressed for the first time, the operation start flag remains OFF and the process proceeds to ST5.

In ST5, the display attributes such as the time (delay time) from the start of the press to the start of the processing of the currently displayed operation button 1 and the set time for sequentially illuminating the number of divisions and divided portions are set. , Operation button attribute storage unit 1
Then, in ST6, the operation start time of the operation button 1 read by the input data reading unit 122 is obtained, and the operation start flag is turned on (ST7). The process further proceeds to ST8, and the current time is acquired from the system time monitoring unit 123.

Next, the process proceeds to ST9, where the sum of the operation start time and the delay time is compared with the current time. Here, if the current time is larger than the sum time (that is, the current time exceeds the sum time), it means that a predetermined delay time has elapsed, and the process proceeds to ST10. A process corresponding to the operation button 1 is started, and a series of controls is ended. However, if the sum time is greater than the current time (ie, the current time has not reached the sum time), it means that the specified delay time has not yet been reached,
At this time, the process proceeds to ST11, where the sum of the time obtained by dividing the delay time by the number of divisions of the operation button 1 and the operation start time is compared with the current time.

In ST11, if the current time is larger than the sum time (that is, the current time exceeds the sum time), t is divided into a predetermined number n of the total delay time t. Since the delay time of / n has elapsed, the process proceeds to ST12 and the display of the operation button 1 is changed. That is, if the operation button 1 is of the type shown in FIG. 1, the value of the counter is changed from 5 in FIG. 1A to 4 as shown in FIG. If it is of the type shown in FIG. 2 or FIG.
(A1), FIG. 2 (b1), FIG. 2 (c1), FIG. 2 (d1)
2 (a2), FIG. 2 (b2), and FIG.
Change as shown in FIG. 2 (c2), FIG. 2 (d2) and FIG. 3 (b) and return to ST2.

However, if the sum time is greater than the current time (ie, the current time has not reached the sum time), t / n is divided into a predetermined number n of the total delay time t.
In this case, the process returns to ST2. If the operation button 1 is continuously pressed, ST3 → ST
4 → ST8 → ST9, and when a delay time of t / n divided into a predetermined number n of the total delay time t elapses, ST
The process proceeds from ST11 to ST12, and the display of the operation button 1 is changed.

When the operation returns to ST2 via ST12, the operation button 1 is kept pressed to return to S2.
T3 → ST4 → ST8 → ST9 → ST11 → ST12 →
The loop of ST2 is repeated several times, and each time the display of the operation button 1 shown in FIGS. 1, 2, and 3 is sequentially changed, the process finally proceeds to ST10 to start the processing corresponding to the operation button 1. Then, a series of control is completed. Here, when the operation button 1 is pressed for the first time, the operation start flag is turned on in ST7, so that "YES" is determined in ST4, and ST5 to ST7 are passed to ST8.
Will go to. Further, if the pressing of the operation button 1 is interrupted in the middle, it is detected in ST3, the operation up to that point is cleared and the operation ends.

Next, the time limit function of the operation button 1 will be described with reference to the flowchart shown in FIG. ST (step) 21 indicates that the operation start flag is OFF as an initial state and that the button counter is 1 as an initial value. Next S
T22 indicates a state of waiting for input of an operation signal when the operation button 1 is pressed. And ST23
Then, it is determined whether or not the operation start flag is ON when the operation button 1 is pressed. Then, when the operation button 1 is pressed for the first time, the operation start flag remains OFF and the process proceeds to ST24.

In ST24, the operation time allowed for the currently displayed operation button 1 (that is, the time limit),
The number of operations set to operate within the time limit (that is, the number of presses), the number of divisions of the operation button 1 and the divided portions are sequentially emitted to display the progress of time, and further, the number of operations is displayed. A display attribute such as a flick is acquired from the operation button attribute storage unit 141. Next, in ST25,
Operation button 1 read by input data reading unit 122
, The operation start flag is turned on (ST26), and the current time is obtained from the system time monitoring unit 123 in ST27.

Next, the process proceeds to ST28, where the sum of the operation start time and the time limit is compared with the current time. If the current time is larger than the sum time (that is, the current time exceeds the sum time), a time-out occurs because a predetermined time limit has been exceeded, and the operation up to that time is cleared. It ends. However, if the sum time is greater than the current time (that is, the current time has not reached the sum time), it is within the time limit and the process proceeds to ST29 to determine whether or not the set number of operations has been reached. Judge.

If the set number of operations has been reached, the process proceeds to ST30 to start the process corresponding to the operation button 1, and ends a series of controls. However, if the set number of operations has not been reached, the process proceeds to ST31, where 1 is added to the button counter, and the display of the operation buttons 1 is changed in ST32 so that the display of the operation buttons 1 at that time is displayed. Thereby, if the operation button 1 is of the type shown in FIG. 1, the counter value is incremented by one to display the number of operations, and the operation button 1 is of the type shown in FIG. 2 or FIG. If there is, one of the divided parts is turned on to display how much time has advanced or how much time remains in the time limit.

When the display of the operation button 1 is changed in ST32, the process returns to ST22. If the second operation button 1 is pressed here, the operation start flag is ON in ST23. Then, the current time is acquired again, and the same operation is repeated thereafter. If the predetermined number of operations is not reached within the time limit, ST
Since a timeout occurs at 28, the operation up to that point is cleared and the operation ends.
